Carbon dioxide Capture and Storage (CCS) is used as a mitigation strategy for addressing the increasing levels of carbon dioxide in the atmosphere. We are working to deliver new approaches, methodologies and tools for the safe operation of offshore CCS sites.
Carbon dioxide Capture and Storage (CCS) has been identified as a possible climate change mitigation strategy as it reduces the amount of carbon dioxide in the atmosphere from the burning of fossil fuels by long-term storage underground. It is however important that we can be confident that the gas will not escape which could pose a threat to the environment. In the ocean elevated levels of carbon dioxide have been shown to increase the acidity of the water, a phenomenon known as ocean acidification, which can have detrimental effects upon marine life.
We are conducting research into the requirements for the environmentally safe and sustainable implementation of CCS projects by developing approaches to enable appropriate marine storage sites to be selected and to monitor them effectively, to increase confidence in CCS as a viable option for reducing atmospheric carbon dioxide.
Our approach combines field experiments alongside laboratory work and mathematical modelling to gain new knowledge to underpin recommendations for future best practice which should benefit a broad range of stakeholders from regulatory bodies, to industry and the wider CCS community.
Making a difference
Our work relating to CCS has made an international impact on industry (e.g. Shell) and policy makers (e.g. DECC), by quantifying and lowering operational risk as well as by proposing cost effective monitoring strategies. With the potential expansion of CCS in forthcoming years, this work has great potential for future application.
